Assertion failure in dequeueReusableCellWithIdentifier:forIndexPath:

by

You’re using the dequeueReusableCellWithIdentifier:forIndexPath: method. The documentation for that method says this:

Important: You must register a class or nib file using the registerNib:forCellReuseIdentifier: or registerClass:forCellReuseIdentifier: method before calling this method.

You didn’t register a nib or a class for the reuse identifier "Cell".

Looking at your code, you seem to expect the dequeue method to return nil if it doesn’t have a cell to give you. You need to use the dequeueReusableCellWithIdentifier: for that behavior:

UITableViewCell *cell = [tableView dequeueReusableCellWithIdentifier:CellIdentifier];

Notice that dequeueReusableCellWithIdentifier: and dequeueReusableCellWithIdentifier:forIndexPath: are different methods. See doc for the former and the latter.

If you want to understand why you’d want to ever use dequeueReusableCellWithIdentifier:forIndexPath:, check out this Q&A.
